Switching The Servomotor Rotation Direction - YASKAWA SGDH User Manual

8.3.2 Switching the Servomotor Rotation Direction

The rotation direction of the servomotor can be switched without changing the reference pulse to the SERVO-
PACK or the reference voltage polarity.
This causes the travel direction (+, -) of the shaft reverse. The output signal polarity such as encoder pulse output
and analog monitor signal from the SERVOPACK does not change.
The standard setting for "forward rotation" is counterclockwise as viewed from the drive end.
Parameter

Pn000
n.
The direction of P-OT and N-OT change. For Pn000 = n.
= n. 1 (Reverse Rotation Mode), clockwise is P-OT.
